The Sekrit BR27 Aktiv Bass Reinforcement Loudspeaker
is a compact yet powerful high performance in-wall bass
reinforcement loudspeaker that can improve and
extend the scope of any high quality loudspeaker
Power amplification is supplied by the included Chakra
amplifier module, which offers high levels of power,
reliability and efficiency, whilst producing less heat and
distortion than traditional amplifiers. This incorporates
signal sensing auto switch-on/off and low standby
power consumption for energy conservation,
advantageous in installs where access to power is limited.
Digitally controlled signal processing and a wide and
adjustable frequency range enable Sekrit BR27 to be
integrated within any environment. Digital controls allow
easy fine-tuning of parameters such as adjustable roll-off,
bass equalisation and phase inversion.
Technological advances derived from Linn's reference
Klimax range have allowed us to develop a bass
reinforcement loudspeaker with the shortest signal
path and maximum headroom, ensuring the most
demanding dynamics from music and movies are
handled with ease and accuracy.
Sekrit BR27 comes supplied with a paintable
loudspeaker grille and MDF baffle and can be built into
walls, ceilings or bespoke cabinetry. It is the perfect
partner for Linn’s other in-wall and in-ceiling loudspeakers
in the Sekrit range and can equally well be used as a
discreet bass solution in conjunction with free-standing
